Re: Creating environments using Guix package manager and collision

[Zelphir Kaltstahl]

I'll have to read up on the `--allow-collisions` flag and see, whether
it does anything dangerous. It sounds dangerous.

I also just noticed, that the conflict seems to have messed up my Guile.
Cannot run Guile any longer, as there is now an issue with readline,
although it is installed:

So I commented out the `(use-modules (ice-9 readline))` and the
`(activate-readline)` from my `~/.guile` file and then it works again.
Perhaps because Guile was updated there is no suitable version of
guile-readline any longer. Guile is now at: 2.9.4.

(That is also something strange, that on one machine I get
`guile-next@2.9.4` and on the other I cannot get a `guile-next` (no
`guix search` result) but can get `guile@3.0.2`. And no matter how often
I run guix pull && guix package -u, it does not appear on the machine
with the older Guile version showing up.)

Thanks for the hint!
